Shadowing an existing "variable": isn't this the normal way how FPLs
"do it"?
It's: the inner (local) environment overwrites the outer environments
and that's, how FPLs are doing it. A new binding to a name.
Should all re-bindings be worth a warning?
if not: which should create a warning, which not?
Is this necessary in pattern matches only?
Ciao,
Oliver
